I In acccrdance-withoneof its objects, them-- -lvention providesimproved meansfor-clampi-ng anlocations. The present invention, in itsillustrated embodiment, provides means for increasing the pressure ofthe band on the-uppefatthe sides oi the toe near its extreme end, theconstruction shown comprising for this purpose" spring-controlled leverswhichare movableabout axes err-3 tending heightwise -of the-lastrelatively to other levers ion which theyare supported and which controlthe endportions of the band. A-further object of the invention'is toprovide means' ior adjusting the band moreefiectively than heretoforefor operating on shoes of different shapes, and to this end theabove-mentioned spring-controlled levers are connected tothe band andare adjustable about their axes to spread variably -1 apart the portionsof the band which they control. It willbe understood that while means isherein shown for thus controlling and adjusting a toe band, theinvention isnot limited tomeans operating at the toe end of a-shoe;

In view of the disclosures in the above-mentioned Letters Patent, onlysuch portions of the complete machine as it is necessary to refer to foran understandingof the novel features of this invention are hereinshown, and such parts as are common to the prior disclosures, as well asthe manner of their operation, will be only briefly hereinafterdescribed. The machine herethe toe end portion of the shoe, theside-lasting mechanisms with which machines of the illustrated type havebeen frequently provided heretofore and the wipers commonly usedheretofore for lasting the heel end of the shoe being omitted.

The last and shoe are supported at the heel end on a block 2 (Fig. 1)having thereon a heel pin or spindle 4 which enters the spindle hole inthe last, the block being supported on the head of a post 6 verticallyadjustable in a holder 8. As in the construction shown in theabove-mentioned Letters Patent No. 2,075,852, the block 2 is freelymovable in the head of the post 6 along guideways II] which extendlaterally of the shoe and are curved about a virtual axis located at ornear the bottom of the heel end of the shoe, so that the shoe may betipped laterally to position the bottom of its forepart in properrelation to the toe wipers. In the construction herein shown mechanismsomewhat difierent from that provided heretofore may be utilized toeffect a quick vertical'adjustment of the post 6 for shoes of differentsizes or styles; This mechanism comprises a pinion 12 fast on a shaft Il mounted in bearings in the holder 8, the pinion being arranged toengage rack teeth I6 on the post 6. Fast on the shaft 14 is a crank armI8 for turning it, this crank arm carrying a spring-pressed pin 26arranged to enter any one of a series of holes 22 provided in a disk 24fast on the holder 8. This holder is supported on a vertically movableslide 26 which is depressible with the shoe as heretofore against theresistance of a spring 28. The toe end of the shoe is supported on a toerest 30 (Figs. 3 and 4) also depressible with the shoe against theresistance of spring means not herein shown but disposedin thelast-mentioned Letters Patent.

Depression of the shoe in the power operation of the machine is effectedas heretofore by means engaging the bottom thereof at the toe and heelends. The means thus acting at the toe end of the shoe comprises apresser foot 32 (Figs. 1 and 12) mounted on a bracket 34 which issupported on an arm 36 and is vertically adjustable by a screw 3'5 (Fig.2). The arm-36 is supported on vertically alined rods 38 and 40 mountedfor vertical movements and for turning movements in bearings in theframe. 'The arm 36 occupies initially a position in which the presserfoot 32 is retracted rearwardly from over the shoe bottom, and theoperator swings the arm forwardly to carry the presser foot intoposition over'the shoe bottom by means of a handle 42. Such forwardmovement of the arm 36 serves to start the power operation of themachine, as disclosed in Letters Patent No. 1,843,232, whereupon the armis carried downward simultaneously with the means engaging the heel endof the shoe to effect the depression of the shoe. The rod 46 (Fig. 2) isswiveled at its lower end in a coupling member 44 which is connected bya link 46 to one end of an arm 48 fast on a rock shaft 58. Also fast onthis rock shaft is an arm 52 provided with a roll 54 engaged by a pathcam 56 formed in one side of a cam wheel 58 on a cam shaft 60. It willthus be seen that by turning movement of the rock shaft 56 the cam 56imparts downward movement to the arm 36 and the toe presser foot 32. Bythe same movement of the rock shaft 56 downward movement is imparted tothe means engaging the heel end of the shoe bottom. This means comprisesa heel presser foot 62 supported by a carrier 64 fast on a rod 66mounted for vertical movements and also for turning movements inbearings in the frame of the machine. Turning movement of the rod 66 toswing the presser foot 62 from an idle position into position over theheel end of the shoe is effected in response to downward movement of therod, as disclosed in Letters Patent No. 1,843,232. The rod 66 isswiveled at its lower end (Fig. 11) in a coupling member 68 which isconnected by a link 16 to one arm of a bell-crank lever 12 mounted forturning movement on a shaft 14, the other arm of this bell-crank leverbeing connected by a link it to' an arm 18 fast on the previouslymentioned rock shaft 50. It will thus be seen that this rock shaftserves to move both the toe presser foot 32 and the heel presser foot 62downward simulteeth 82 on the rod. The pinion is formed on a shaft 84mounted in a bearing in the carrier 64,

and fast on one end of this shaft is an arm 86 for turning it. Carriedby the arm 86 is a springpressed pin 88 arranged to enter any one of aseries of holes in the carrier 64 to hold the presser foot in adjustedposition. A series of numbers opposite the holes 90, as shown in Fig. l,assist the operator in determining when the presser foot is properlyadjusted.

The toe-lasting mechanism includes as heretofore, a slide 92 (Fig. 1)adjustable in directions lengthwise of the shoe, and a casting 94adjustable on the slide 92 about an axis extending laterally of theshoe. Supported on the casting 94 is means generally similar to thatdisclosed in the previously mentioned Letters Patent No. 2,075,852 forclamping the upper around the toe end of the last and for wiping theupper upwardly as the last and shoe are forced downwardly in themanner'above described. This means comprises a block 96 (Fig. l) fast onthe casting 94 and serving as a support for a pair of levers 98pivotally mounted between their ends on pinsgI00 on the block 96. Acomparatively long arm of each lever 98 serves as a support for a blockI02 which inthe construction herein shown has a cylindrical shankportion I04 (Fig. 5) mounted in a bearing in the lever 98to permit theblock to turn about an axis extending heightwise of the shoe.

The two blocks I02 have inclined slots therein to receive the the endportions of a flexible toe band I08 for engaging the shoe and wiping theupper upwardly. Supported on the upper fiat face of the block 96 areapplurality of slides extending in a series lengthwise of the edge ofthe shoe bottom between the two blocks I 02 and also having inclinedslots therein to receive the band I06. As shown in Fig. 4, there are sixof these slides I08 located opposite the end of the toe of the shoe, andbetween these slides and each block I02 are three additional slides H0,H2 and H4 located opposite the sides of the toe. The several slides arecontrolled by a coil spring IIB extending around the toe and mounted inrecesses in their outer sides in the manner illustrated in Fig. 7.

This spring tends to force the slides inwardly toward the shoe whilepermitting them to be forced outwardly by pressure of the shoe on thetoe band. The end blocks I02 are also'yieldingly controlled asheretofore to permit them to be forced apart by wedging action of theshoe on the hand. For this purpose a comparatively short arm of eachlever 98 has rotatably mounted therein a stud H8 provided below the armwith a block I20 through which extends a rod I22, one end of this rodhaving thereon screw threads engaging corresponding threads in one ofthe blocks and the intermediate portion of the rod being mounted to turnin the other block. A spring I24 located between the last-mentionedblock I20 and a .ot e toadiust the ends of: e. b nd r shoes differentwidths. It will further be evident that both the band-supporting armsmay swing in the same direction laterally of a shoe to permit the bandto adjust itself to the toe ends of right and left shoes the heel endsof which occupy substantially the same positions in the machine.

By reference to Fig. 4 it will be evident that the coil spring H6, byreason of its relation to the different slides which it controls,opposes somewhat less resistance to outward movements of the slides H0,H2 andII4 located opposite the sides of the toe near its extreme endthan to outward movements of the slides I08 opposite the end of the toe.The present invention accordingly provides means for'increasing theresistance to outward movement of the slides H0, H2 and I I4. For thispurpose there is supported on a lug I32 (Fig. 5) on the end of each ofthe band supporting arms of the levers "98 a bell-crank lever I34mounted to swing about a pin I 38 extending through the lug. An arm I38of this.

bell-crank'lever is pivotally connected by a stud M0 (Fig. 4) to a blockI42 the opposite ends of.

which are pivotally connected by studs I44 and M6 to the slides H0 andH4, respectively. It will thus be seen that the arm I38 is connected toboth these slides by means permitting relative inward or outwardmovements of the two slides. Mounted in the other'arm I48 of thebell-crank lever I34 is a spring I50 one end of which is seated in asocket in the block I02. This spring accordingly tends to swing thebell-crank'lever in the direction to force the slides I I0 and H4inwardly toward the shoe, and therefore opposes increased resistance tooutward movements of these slides. While notdirectly connected to theslide I I2, the block I42 controls this slide through the comparativelystiff toe band I06 mounted in slots in the several slides. A screw I52threaded in each bell-crank lever I34 is arranged to engage an arm I54integral with the lever 98 to limit movement of the bell-crank lever bythe spring I50 when'there is no shoe in the machine. These screws servein addition to the hand wheel I30 to adjust the toe band for shoes ofdifferent shapes. .By turning the screws, for example, in

directions to swing the bell-crank levers I34 against the resistance ofthe springs I50 the slides H0 and II 4 are moved in outward directionsto spread farther apart portions of the toe band located opposite thesides of the toe near the end thereof without affecting the spacing ofthe ends of the band controlled by the hand wheel I550. The studs I40are mounted in the blocks I42 somewhat nearer the slides [I0 than theslides II l, so that the levers I34 in this adjustment of the toe bandact with greater force on portions of the band located substantiallyopposite the corners of the toe than on portions controlled by theslides II4.

The construction herein shown includes means for adjusting thetensionof, the coil spring H6 shoe. For this purpose each end of the sprin'gisconnected by a wire loop I58 to an eye-bolt I58 mounted in a lug I60 onthe bell-crank lever I34 .an eccentric an axis located substantially atthe junction of 1 their wiping edges. The wiper carrier is provided asheretofore with a thin plate I'IU, shown in dotted lines in Fig. 3,which underlies portions of the wipers and moves with them over the endof the toe so that no portion of the margin of the upper at the end ofthe toe will be exposed and therefore relieved of pressure when thewipers close. In order to hold this thin plate firmly against the marginof the upper the wipers have interlocking portions comprising, on eachwiper, a plurality of curved fingers I72 'whichextend into correspondingrecesses in the other wiper when the wipers are in their open positionsand hold the plate I10 pressed down on the upper in locations atdifferent distances from the edge of the shoe bottom when the wipers areclosed over the shoe bottom. The wiper carrier IE6 is operated toadvance the wipers lengthwise of the shoe by a gear sector I'M fast on arock shaft I16 mounted in the casting 94 and operated by the same meansas heretofore in machines of the illustrated type. The wipers are closedlaterally of the shoe by slides I18 mounted in guideways in the casting94 and operated by rack bars I813, these rack bars being operated bygear sectors I82 on the rock shaft I16. In the construction herein shownthese rack bars are connected yieldingly to the slides IIB for a purposehereinafter described. The yielding connection between each rack bar andslide comprises a spring I84 mounted between one end of the slide and anupstanding lug I86 on the rack bar. Extending through the lug and thespring and threaded in the slide I78 is a screw I88 the head of whichserves by engagement with the lug I86 to determine the initial relationof the rack bar and the slide.

The connections between the slides I78 and the wipers are substantiallyas disclosed in Letters Patent No. 2,075,852. Each slide is connected bya link I90 to a member I92 mounted to turn about I96 controlled ashereinafter described, and the member I92 is connected by a link I and apivot pin I98 to the wiper I64. It will thus be seen that as the wipersare advanced lengthwise of the shoe they are closed laterally of theshoe by the slides I18 which act thereon through the links I913, themembers I92 and the links I95, the members I92 turning about theeccentrics I95. The eccentrics I93 are parts of mechanisms of the samecharacter as disclosed in the last-mentioned Letters Patent for swingingthe two wipers IM simultaneously in one direction or the other about theaxis of their closing movements to adjust them in accordance with theswing of the forepart of a. right or a left last in response to asimilar swinging movement'of the toe band I86 when a shoe is forceddownwardly within the toe band. Each of these mechanisms includes a link208 one end of which is connected to one of the band-controlling levers98 through an upward extension of the pin I35, as shown in Fig. 5, theother end of the link being connected to a plate 202 which is integralwith the eccentric I94. Accordingly, if the end poritions of the toeband I06 are swung, for example to the right (Fig. 3) by the action ofthe shoe movement of the band to turn the eccentrics I9 1 incounterclockwise directions, and by such movements of the eccentrics themembers I92 mounted thereon areswung about their connections with thelinks I58 and act through the links I95 to swing the wipers I64 in thesame direction as the ends of the toe band. Thereafter, as the wipersbegin their operative movements, the eccentrics I94 are locked againstany such displacement as might affect the pressure of the toe band onthe shoe by pawls 204 acting on ratchet teeth on the plates 202. Thesepawls are held out of engagement with the ratchet teeth by the action ofthe links I90 on screws 2% on the pawls until the slides I'EB begintheir operative movements, whereupon the pawls are forced against theratchet teeth by springs 208.

The bottom of the forepart of a last is usually somewhat convex indirections widthwise of the last, as shown in Fig. 5. It will be evidentthat if such a last is held stationary relatively to wipers operating ina single plane the pressure of the wipers on the margin of the upperwill increase progressively as the wipers are moved inwardly over theinsole if the wipers engage the upper initially at the extreme edge ofthe insole. The present invention further provides a construction suchthat the wipers, acting on the upper with adequate pressure at theextreme edge of the insole, will not apply excessive pressure thereto asthey are moved farther inwardly. For this purpose the cam 56 (Fig. 2)which, as previously described, imparts the shoe-depressing movement tothe toe presser-foot 32 and the heel presser-foot 62 is so formed, asindicated at a, as to depress the shoe somewhat during the overwipingmove-' ment of the wipers. The toe presser-foot 32 will be so adjustedthat when the wipers begin to wipe the margin of the upper inwardly overthe insole they will apply adequate pressure thereto, as illustrated inFig. 6, and by the action of the cam 56 as they are moved fartherinwardly the shoe is depressed sufficiently to cause the pressure of thewipers on the upper to remain substantially uniform, as illustrated inFig. 5. Further to insure this result at both sides of the shoe bottom,each wiper'in the construction herein shown carries a, roll 2H) arrangedto engage a shoulder 2 I 2 on the block I92 which supports the toe band.The closing movements of the wipers, therefore, are limited by the shoeso that they will close inwardly equal distances from the opposite sideedges of the shoe bottom. When the movements of the wipers are thusstopped, any further movement of the rack bars I89 serves merely tocompress the springs I84.

As in the construction shown in Letters Patent No. 2,075,852, the wipersI 64 are maintained in a heated condition to render them more effectivein'wiping the margin of the upper free from wrinkles and to acceleratethe hardening or setting of adhesive whereby the upper is secured to theinsole. For this purpose there are provided electrically heated plates2M (Figs. 2 and 5) fastened 'to a cover plate on the casting 94 and insliding contact with extended fiat upper faces 2I6 (Fig. 3) on the linksI96, these links having also lower fiat faces in sliding contact withthe wipers. For better insurance of effective contact of the heatingplates 2M with the links and of the links with the Wipers, there arefastened to the casting 94 upwardly extending brackets 2I8 and 220 (Fig.2) the upper ends of which extend to positions over'th'e portions of theplates 2I4 which'engage' the links I96 and carry set screws bearingdownwardly on these plates. The set screw on the bracket 2 l 8 is shownat 222 in Fig. 2, and the set screw on the bracket 228 is shown at 224in Fig. 5. It will be understood that these screws may be adjusted asdesired. ,7

- The machine is further provided with means constructed for the mostpart as shown in Letters Patent No. 2,075,852 which, by engagement withthe bottom of the forepart of the shoe, will tip the shoe laterally toinsure that both sides of the toe end of the shoe bottom will be at thesame height relatively to the Wipers if the shoe is not already properlypositioned in that respect. This means comprises a member 226 (Figs. 2and 12) formed to engage'the opposite sides of the forepart of the shoebottom and mounted for upward and downward swinging movements on thepreviously mentioned bracket 34 on the arm 36. This member is controlledby two pivotally connected links 228 and 230 which are held normally insubstantialalinement by a spring 232 toposition the member 226 forengagement with the bottom of the shoe before the presser foot 32engages it. The shoe is thus properly positioned by the member 226before it is moved downward to any substantial extent, whereupon thismember is withdrawn from contact with the shoe bottom by swinging thelinks 228 and 230 out of alinement, as illustrated in Fig. 12. For thispurpose the link 236 is fast on a shaft 234 mounted in the bracket 34,and also fast on this shaft in the construction herein shown is an arm236 (Fig. 2) provided with a roll 238- arranged to engage the top faceof a 35 relatively stationary block 246 just as the shoe is properlypositioned by the member 226, so that in the further downward movementof the arm 36 the member 226 will be lifted by the turning of the shaft234. The block 248 has a depending portion movable in a guideway in thepreviously mentioned bracket 220, as shown in Fig. 3, and the block isadjustable upwardly or downwardly by means of an arm 242 mounted on apin 244 on the bracket 226, the arm being provided with a stud 246 whichextends into a slot in the. depending portion of the block. The arm 242carries a spring-pressed pin 248 arranged to enter any one of a numberof holes in the bracket 220 to maintain the block 246 in adjustedposition.

In general similarityto the disclosure of Letters Patent No. 2,075,852,the machine herein shown is also provided with means for pressing thetoe end of the insole down on the bottom of the last and for engagingthe margin of the upper in the-path of the toe wipers I64 and pressingit against the wipers for better insurance that the upper will be wipedtightly and smoothly inward over the insole. This means comprises amember 256 (Figs.

'1, 12 and 13) curved'in general similarity to the edge of the toe endof the insole and supported on a yoke 252 which is yieldable upwardlyagainst the resistance of a spring 254 in the handle 42. As shown inFig. l, the member 258 is positioned initially somewhat lower than thepresser foot 32 to insure that it will engage and press the toe end ofthe insole down on the last under the influence of the spring 254. Asshown in Figs. 12 and 13, the member 256 in its operative position onthe insole is in the path of the toe wipers so that it "will press themarginof the upper against thebe lifted against the resistance of thespring 254 by the wedging action of the wipers thereon to permit themargin of the upperto be wiped down upon the insole beneath it.

Reference has previously been made herein to the fact that the toewipers are automatically adjusted about an axis extending heightwise ofthe shoe through connections with the toe band I06 so as to assumedifferent positions for operating on right and left shoes. To insurethat the member 250 will press the margin of the upper effectivelyagainst the edges of the wipers all around the toe end of the shoebottom in operating on either a. right or a left shoe, this member inthe construction herein shown is so supported on the yoke 252 as topermit it to be adjusted about an axis extending heightwise'of the shoein response to pressure of the wipers thereon. For this purpose themember 250 is mounted on a block 258 (Fig. 12) provided with an upwardlyextending pin260 rotatable in a socket in the yoke 252. Accordingly, ifthe member 250 is not positioned symmetrically with respect to the toeend of the insole, pressure of one or the other of the wipers against itin the wiping of the margin of the upper inwardly over the insole willturn it to such a position about the axis of the pin 268, as will beevident by reference to Fig. 13. The member 250 is also movable asheretofore about an axis extending laterally of the shoe to permit it toadjust itself to the shoe bottom, the member and the block 258 beingconnected for this purpose by- A spring 264, connected at one a pivotpin 262. end to the yoke 252 and at its other end to the member 250 atthe left-hand side (Fig. 12) of the pin 262, serves normally to supportthe member and the block 258 on the yoke and also tends to centralizethe member with respect to turning movement about the axis of the pin26!). In order to render the spring 264 more effective in' the latterrespect, it is engaged at its opposite ber 250 which are locatedfarthest from the endof the toe. This is advantageous if. as shown. thepin 262 is located comparatively near that portion of the member 250which is at the extreme e d of the toe, since if it were not for thesprin'g'264 the member 250 under these conditions would act withsomewhat less pressure on the shoe materials in locations farthest fromthe end of the toe than in other locations.

The shoe is clamped about its heel end, as heretofore, bya flexible heelband 268 whichassists in controlling it in the toe-lasting operation,this heel band being carried by a slide 210 movable in directionslengthwise of the shoe along rods 212, one of which is shown in Fig. 1,supported by the vertically movable slide 26. In the construction hereinshown the heel band is supported at its ends by twr arms 214 (Figs. 1and 8) mounted to swing about pins 216 on a bracket 218 which isprovided with a horizontal stem 280 rotatable in a socket formed in aholder 282., The intermediate portion of the band is Between the innerend of the stem 288 and the end of the socket in the holder 282 is aball thrust bearing 284. The stem 288 is held in the socket by a capscrew 286 extending through an opening in the holder 282 and threaded inthe end of the stem. This construction permits the heel band 268 to turnabout 'an axis extending lengthwise. of the shoe when the shoe is tippedlaterally by the forepart-engaging member 226 as previously described,and accordingly facilitates such tipping of the shoe. The holder 282 hasa depending shank portion 288 vertically movable in a guideway in theslide 218 to permit adjustment of the heel band in directions height-Wise of the shoe for shoes of different sizes or shapes. Such adjustmentis effected by an arm 298 (Fig. 8) mounted for vertical swingingmovements about a stud 292 on the slide 210 and provided with a pin 294lying in a horizontal slot 296 in the shank 288. A-spring-pressed pin298 carried by the arm 298 is arranged to enter any I one of a number ofholes 388 in the slide 216 to hold the heel band in adjusted position.Any turning movement of the heel band about the axis of the stem 280 iseffected against the re- :sistance of a comparatively light leaf spring382 the upper end-of which lies in a slot formed in a depending lug 384of the bracket 218 and the lower end of which is secured to lugs 386 onthe depending shank portion ,288 of the holder 282.

The heel band 268 is held initially in a retracted position, asheretofore, by a latch 383 (Fig. -1) in engagement with a shoulder onthe lower end of the slide 218, and this slide and the heel band aremoved toward the shoe by a spring 3"] when the slide is released by thelatch. Such release is effected by the operator prior to the starting ofthe power operation of the machinerby downward movement of an arm 3l2which carries the latch, this arm being mounted on a stationary bracket313. The holder 8 which supports the last pin 4 as hereinbeforedescribed is movable in directions lengthwise of the shoe along aguideway in the slide 26, and is controlled by a spring 3! actingthereon through a link 3 l6, as more fully disolosed in Letters PatentNo. 2,026,539, granted on January '7, 1936 upon an application of mine.A latch 3l8 is arranged to maintain the holder 8 initially retractedfarther to the left than shown in Fig. 1, and near .the' end of themovement of the slide 210 by the spring 3| 8 to carry the heel bandtoward the shoe a screw 328 carried by this slide acts on the latch 3I8to release the holder 8 to the action of the spring 3l4, whereupon thisspring moves the g holder toward the right and forces the heel end ofthe shoe against the heel band. For a more complete understanding of theconstruction and operation of these parts the last-mentioned LettersPatent may be referred to.

; 1 As disclosed in the previously mentioned Letters Patent No.1,843,232, the machine is provided with automatic means for removing theshoe fromthe shoe support after the lasting operations have beencompleted, comprising an os- 5.cillatory shoe-carrying arm 322 (Fig. 11)having thereon a shoe-gripping device 324, the arm being mounted on arock shaft 326 for swinging movement into position for the device 324 togrip the shoe on the shoe support and for reverse 70 swinging movementto carry the shoe to a position in which it is released. The arm isswung into position to grip the shoe by downward movement of a rack bar328 engaging a pinion 333 on the rock shaft 326, the downward movement75. of the rack bar being effected by similar movement of a link 332connected to its lower end. The removal of the shoe from the shoesupport is effected by reverse upward movement of the rack bar and thelink. In order to insure that the heel band will be withdrawn from theshoe 5. before the device 324 arrives in position to grip the shoe,movement of the slide 218 toward the right (Fig. 1) into position to beheld by the latch 388 is effected by the downward movement of the link332, as disclosed in Letters Patent 10 No. 1,979,269, granted onNovember 6, 1934 upon an application of mine. For this purpose the link332 carries an arm 334 which in the downward movement of the linkengages a turn-buckle 336 on a rod 338 connected by a chain 348 to the15 slide 218. It is desirable, however, that no return movement towardthe left (Fig. 1) be imparted to the last pin holder 8 until after theshoe has been removed from the shoe support by the reverse swingingmovement of the arm 322 effected by 20,

upward movement of the link 332. Accordingly, in the construction hereinshown the arm 334 is further utilized to effect such return of theholder 8 when the arm has nearly completed its upward movement, the shoehaving then been 25;

removed from the shoe support. The previously mentioned link 3|6connected to the holder 8 is pivotally connected to an arm 342 (Fig. l)mounted to swing on the bracket 3l3 and geared to another arm 344 alsomounted to swing on the 30,.

the arm 344. As the parts are shown in Fig. 1, 40,

the bar 346 is at such a height that the plate 354 is at the right ofthe plate 356. Near its lower end the bar 346 is provided with a secondslot 358 in which lies a pin 368 carried by the arm 334, this pin havinga head thereon to hold the 457 bar. in proper relation to the arm. Aspringpressed pin 362 in the lower end of the bar 343 serves as a bufferupon engagement of the pin 368 therewith in the downward movement of thearm 334. By reference to Fig. 11 it will be seen that with the partspositioned as indicated in Fig. 1, the heel band having been applied tothe shoe and the holder 8 released by the latch 3l8, the pin 348 issubstantially midway between the upper and lower ends of the slot 358and the pin 368 is at the upper end of the slot 358. Accordingly, whenthe arm 334 is moved downwardly during the swinging of the shoe-removingdevice toward the shoe and acts through the rod 338 to return the slide218 which carries the heel 0.

band, the pin 368 is first moved downwardly along the slot 358 andthereafter acts to lower the bar 348 to such a position that the plate354 at its upper end snaps under the plate 356 on the arm 344. Suchdownward movement of the bar is limited by the pin 348. When the arm 334is thereafter moved upwardly as the shoe is carried away from the shoesupport, the pin 368 first moves idly along the slot 358 until itarrives at the upper end of the slot and then serves to raise the bar346. As the bar is thus raised its plate 354 acts on the plate 356 toswing the arm 344 in the direction to return the holder 8 toward theleft into position to be held by the latch 3l8. Further upward movementof the A leaf spring 352 fast on 35;

bar 346 thereafter causes the plate354 to slip past the lower edge ofthe plate 356, thus releasing the arm 3% so'that when the latch 3l8 isoperated to release the link 316 in operating on the next shoe theholder B will be free to be moved toward the right by the spring 3 I4.

-The manner of operation of the novel mechanisms provided by the presentinvention will be fully understood from the foregoing description, andaccordingly no further explanation thereof is necessary for a fullunderstanding of the invention.
